The results indicated that the essential oils had the antifungal activities against five fungi at the concentration of 1 g/L. Especially the antifungal activities of the essential oil from Clausena lansium was excellent against Phyricularia grisea, and the inhibition rate was 93.85% at 1 mg/mL; The EC50 of the essential oil from Clausena lansium was 0.21 g/L against Botryodiplodia theobromae.
